Standard Loading Profile in Matrix Rigidity Sensing [PDF]
Biophysical Journal, 2018 It is important to learn features of locally applied forces by cells during matrix rigidity sensing, since the function of mechanosensing proteins would be affected by force magnitude, loading velocity, or even loading history. Here, we investigate a rigidity-sensing apparatus consisting of a contractile unit on matrices.

Rigidity percolation in dispersions with a structured viscoelastic matrix [PDF]
Physical Review E, 2005 This paper deals with rigidity percolation in composite materials consisting of a dispersion of mineral particles in a microstructured viscoelastic matrix. The viscoelastic matrix in this specific case is a hydrocarbon refinery residue. In a set of model random composites the mean interparticle surface-to-surface distance was controlled, changing ...

Extracellular matrix rigidity modulates neuroblastoma cell differentiation and N-myc expression
Molecular Cancer, 2010 Neuroblastoma is a pediatric malignancy characterized by tremendous clinical heterogeneity, in which some tumors are extremely aggressive while others spontaneously differentiate into benign forms.

Matrix rigidity regulates cancer cell growth by modulating cellular metabolism and protein synthesis. [PDF]
PLoS ONE, 2012 Tumor cells in vivo encounter diverse types of microenvironments both at the site of the primary tumor and at sites of distant metastases. Understanding how the various mechanical properties of these microenvironments affect the biology of tumor cells ...

Kronecker Products, Low-Depth Circuits, and Matrix Rigidity [PDF]
SIAM Journal on Computing, 2021 For a matrix $M$ and a positive integer $r$, the rank $r$ rigidity of $M$ is the smallest number of entries of $M$ which one must change to make its rank at most $r$. There are many known applications of rigidity lower bounds to a variety of areas in complexity theory, but fewer known applications of rigidity upper bounds.

Matrix Rigidity Depends on the Target Field.
, 2021 The rigidity of a matrix A for target rank r is the minimum number of entries of A that need to be changed in order to obtain a matrix of rank at most r (Valiant, 1977). We study the dependence of rigidity on the target field. We consider especially two natural regimes: when one is allowed to make changes only from the field of definition of the matrix
